In the present work, laser induced shock wave on different materials was studied, the used materials is [Paramagnetic metal (Stainless steel 304) and Ferro magnetic metals (Iron)]; immersed in some media (air and water) to study the media effect on its properties. These materials are irradiated by using different laser intensities. Laser induced shock wave was achieved by employing Nd-YAG laser at wavelength 1064 nm. X-ray diffraction revealed shifting in diffracted angles of Fe toward higher angles due to phase transformation where in air transition from Austenite to Martensite while in water from Martensite to Martensite has smaller grain size because high generated temperature followed by quenched, the diffracted angle of S.S.304 metal shifted toward very little value due to twining effects where high stress and strain are produced.
